>Description</H2
><P
>   <CODE
CLASS="FUNCTION"
>SPI_connect</CODE
> opens a connection from a
   procedure invocation to the SPI manager.  You must call this
   function if you want to execute commands through SPI.  Some utility
   SPI functions can be called from unconnected procedures.
  </P
><P
>   If your procedure is already connected,
   <CODE
CLASS="FUNCTION"
>SPI_connect</CODE
> will return the error code
   <SPAN
CLASS="RETURNVALUE"
>SPI_ERROR_CONNECT</SPAN
>.  This could happen if
   a procedure that has called <CODE
CLASS="FUNCTION"
>SPI_connect</CODE
>
   directly calls another procedure that calls
   <CODE
CLASS="FUNCTION"
>SPI_connect</CODE
>.  While recursive calls to the
   <ACRONYM
CLASS="ACRONYM"
>SPI</ACRONYM
> manager are permitted when an SQL command
   called through SPI invokes another function that uses
   <ACRONYM
CLASS="ACRONYM"
>SPI</ACRONYM
>, directly nested calls to
   <CODE
CLASS="FUNCTION"
>SPI_connect</CODE
> and
   <CODE
CLASS="FUNCTION"
>SPI_finish</CODE
> are forbidden.
   (But see <CODE
CLASS="FUNCTION"
>SPI_push</CODE
> and <CODE
CLASS="FUNCTION"
>SPI_pop</CODE
>.)
